PKP class Pm36 is a class of two express passenger (P) 4-6-2 (m) steam locomotives ordered in 1936 for the Polskie Koleje Państwowe (Polish State Railways). History Design The design was ready in 1936 and the following year the first two prototypes were built. One of them (Pm36-1) had aerodynamic fairing. The construction as well as the shape of it was designed by inz. Kazimierz Zembrzuski, head of the design office in the First Polish Factory of Locomotives and at the same time professor of the Warsaw University of Technology. The other (Pm36-2) had a standard look. The idea was to test both engines in parallel to compare top speed, acceleration, coal and water consumption etc. The Pm36-1 won a gold medal at the 1937 International Exposition of Art and Technology in Paris.
